OBTURATIL NG DEVICE FOR NON-REFILLABLE FLASKS OR THE LIKE.

Application filed March 15, 1918.

T0 alZ whom it may concern:

Be it known that 1, Luis ARNAVAT OLIVE, a citizen of the United Statesof America, and a resident of Habana, Republic of Cuba, have inventedcertain new and useful Improvements in Obturating Devices for Non-Refillable Flasks or the like, of which the following is aspecification.

This invention relates to the receptacles of a non-refilling nature orthat can not be refilled once its contents have been removed and itsobject is to provide an obturating device which is applied in the lowerpart of the neck of flasks, jars, glasses and generally to anyreceptacles of any shape that are used for containing products in afragmentary, granular or powdered condition, this obturating devicebeing so disposed thart it easily permits the discharge of the containedproducts but that at the same time may prevent the introduction of newsolid matter in the receptacles thereby protecting same against thefalsification that would result from the fraudulent refilling of thereceptacles done after the original products contained therein have beendischarged, whereby this invention results in a very advantageousapplication 1n the sale of such pharmacal products of a fragmentary,granular and powdered character.

The invention is described with reference to the figures of the annexeddrawings, 1n which:

Figure 1 is a vertical section of an obturating device made of differentPieces, applied in the neck of a flask.

Fig. 2 is a vertical section of the same obturating device made of anintegral piece.

Fig. 3 is an upper plan view of the upper piece of said obturatingdevice.

Fig. 4 is a vertical section on line 4-4 of Fig. 3.

Fig. 5 is an upper plan view of the intermediate piece of saidobturatlng device.

Fig. 6 is a vertical section on line 6--6 of Fig. 5.

Fig. 7 is an upper plan v 1ew of the lower piece of said obturatingdevice.

Fig. 8 is a vertical section on line 8-8 of Fi Fig. 9 is a verticalsection of a modified form of obturating device applied to the neck of aflask.

Fig. 10 is an outer elevation of same obturating device.

Serial No. 222,671.

And Fig. 11 is a vertical section on line other by means of a pluralityof inclined surface conduits terminating at said openings, the loweropening 2 being closed by means of an inclined door 3 which by virtue ofthe gravity force, tends to maintain closed said lower aperture.

In Fig. 1 of drawings, the chamber constituting the obturating device isformed by three pieces, an upper piece 4, an interme diate piece 5 and alower piece 6 all of which are of different height or depth and they mayhave in horizontal section a circular shape as shown in the drawings, orpolygonal such as square, rectangular, etc., always in conformity to theshape of the horizontal section of the neck 7 of the flask within whichsaid obturating member is adjusted by means of a small sleeve 8 of corkor any other suitable material, whose upper edge is covered on theoutside by a rim or flange 9 laterally projecting from the upper piece4. This upper piece has a vertical conduit 10 leading downwardly fromopening 1, and one of whose sides forms an inclined surface 10"terminating in a wide opening 1 in the lower part of said upper piece 4.The intermediate piece 5 presents a vertical opening 5 disposeddiametrally opposite the opening 1 of the upper piece 4 and laterally tosaid opening 5 there is formed a recess 11 limited by an inclined plane11 that leads from the end of the lower opening 1 of the upper piece 4diametrally opposite to opening 5 and terminating in this one. The lowerpiece 6 presents an opening or vertical conduit 2 located diametrallyopposite the opening 5 of the intermediate piece 5 and which is closedon the top by means of an inclined door 3 mounted on a hinge 12 at itsuppermost part, and from said vertical opening openings 1 and 2communicating with each 4 1n grooves 16 provided in the lower face ofpieces 4 and 5 respectively. Once the obturating device is adjusted withthe sleeve 8 a common cork plug 21 is placed upon the same.

In Fig. 9 of the drawings a modified form of the obturating device hasbeen shown in which said device consists of two pieces 4 and 6 which areequivalent to the upper and lower pieces of the form shown in Figs. 1and 2 of the drawings, the intermediate piece 5 having been omitted. Theupper piece 4 is similar to the upper piece previously described. Thelower piece 6 is rovided with an opening or vertical conduit 2 which isdiametrally opposite to opening 1 of the upper piece and it is closed bymeans of an inclined door 3 mounted on a hinge 12 at its uppermost part,and from which there is an upwardly directed vertical conduit 13, one ofwhose sides forms an inclined surface 13 leading from the lowermost partof said door 3 to the opposite end of the lower opening 1 of said upperpiece 4:. In this case there are provided lateral nerves 18 in the lowerpart of conduit 10 of the upper piece 4, intended to constituteengagingsurfaces for the door 3 in its upward swinging movement.

In Figs. 10 and 11 there is shown a modifled form of engagement betweentwo successive pieces, and which consists of two vertical lugs 19diametrally opposed provided in the. upper face of the lower piece andwhich fit in corresponding cuts 20 formed 011 the peripheral surface ofthe upper piece.

Once the flask is filled with the product that is to contain, thedescribed device is placed in the lower part of the neck and thereuponthe product in question might be discharged from the flask but it wouldnot be possible to refill it again. In eflect, in the form shown inFigs. 1 and 2 when the flask is inclined to pour out a certain amount ofthe product, the door 3 is automatically raised and the product passesthrough opening 2, then slides upon the inclined surface 13 toward theintermediate opening 5 wherefrom it slides again upon inclined surface10 until reaching opening 1 wherefrom it comes out. However, if it isintended to fill up the flask again, the product would pass throughconduit 10 and opening 5 and would slide upon the inclined surface 13until falling on the door 3 that would be caused to close by reason ofthe weight of the product itself gravitating upon said door, withoutbeing able to enter the interior of the flask.

In the form shown in Fig. 9 if it is intended to refill the flask theproduct would fall directly on the inclined surface 13 gravitating upondoor 3 thus preventing same to swing outwardly, whereby the introductionof the product is'thus prevented.

IVhat I claim is:

A non-refillable receptacle including a neck, a plug, provided with apassage, in said neck, an abutment extending from the side wall of saidpassage into the same, the passage making an acute bend around saidabutment, a flap valve hinged below said abutment, and a second abutmenthaving its outer edge below the plane in which said flap valve ishinged, such second abutment extending into the passage from theopposite side thereof and being adapted to have its outer edge engagedby the outer edge of the valve.

In testimony whereof I affix my signature in presence of two witnesses.
